What role did the USGS play in the 1997 Hollywood production of the movie Dante’s Peak?

The digital elevation perspective model of Mt. St. Helens, Washington, produced by the USGS in Menlo Park, California, had a bit part in the movie. The model was a 100 square-foot by 35 foot-high wood and steel structure built on a sound stage in Los Angeles, California. Computer-generated gas, steam, ash, and lava were created as special effects.
